Hungaresia Szorenyi, 1955, p. 76

[Pseudovulechinus Szorenyi, 1955, p. 79, type species Pseudovulechinus rotunatus Szorenyi, 1955 (=Galerites ovum Grateloup, 1836, p. 157)]

Diagnostic Features
  • Test large, elongate, well rounded anterior and posterior margin, highly inflated adapical surface, flat adoral surface with sharp margin and steep sides.
  • Apical system tetrabasal, with large madreporite and small genital plates anterior according to Kier (1962).
  • Petals long, open, narrow, parallel, with wide poriferous zones with conjugate pores, outer pore elongated transversely, inner pores circular.
  • Peristome strongly anterior, pentagonal, opening invaginated.
  • Periproct inframarginal, longitudinally oval.
  • Phyllodes widened, single pored, with two series of pores in each half-ambulacrum.
  • Bourrelets: basicoronal plates short. Phyllodes sunken creating 'pseudobourrelets' which incorporate post-basicoronal plates, forming weakly rounded mounds close to peristome.
  • Buccal pores present.
  • Narrow naked zone running from peristome to periproct, covered in fine granules.
Distribution
Upper Cretaceous (Coniacian-Maastrichtian) of Hungary and Pakistan.
Name gender feminine
Type
Hungaresia hungarica Szorenyi, 1955, p. 77 (=Galerites ovum Grateloup, 1836, p. 157); by original designation.
Species Included
  • Hungaresia ovum (Grateloup, 1836); Coniacian-Santonian, Europe.
  • Hungaresia helios (Noetling, 1897); Maastrichtian, Pakistan.
Classification and/or Status
Irregularia; Cassiduloida; Echinolampadidae.
Remarks

Kier (1962) synonymized Hungaresia with Vologesia, but as pointed out by Smith (1995) the type species of Vologesia (V. tataosi) is very different in having little or no bourrelet development, and has shorter denser pored phyllodes. This genus is distinguished from Clypeolampas on the simpler structure of its phyllodes (Smith & Jeffery, 2000).
